$$\cot{\left(6 x \right)} = \frac{\sqrt{3}}{3}$$
Solución detallada
Tenemos la ecuación
$$\cot{\left(6 x \right)} = \frac{\sqrt{3}}{3}$$
cambiamos
$$\cot{\left(6 x \right)} - 1 - \frac{\sqrt{3}}{3} = 0$$
$$\cot{\left(6 x \right)} - 1 - \frac{\sqrt{3}}{3} = 0$$
Sustituimos
$$w = \cot{\left(6 x \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
-1 + w - sqrt3/3 = 0

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w - \frac{\sqrt{3}}{3} = 1$$
Dividamos ambos miembros de la ecuación en (w - sqrt(3)/3)/w
w = 1 / ((w - sqrt(3)/3)/w)

Obtenemos la respuesta: w = 1 + sqrt(3)/3
hacemos cambio inverso
$$\cot{\left(6 x \right)} = w$$
sustituimos w:
